Pennsylvania Castle Estate crowns the Isle of Portland in Dorset on the celebrated Jurassic Coast, a Grade II Listed Gothic Revival mansion constructed between 1797 and 1800 by renowned architect James Wyatt. The castle was built by John Penn, son of William Penn, who was enchanted by Church Ope Cove after discovering it with King George III. Its dramatic clifftop setting commands breathtaking views across the Dorset coastline and English Channel, and the estate has hosted illustrious visitors including Winston Churchill, Dwight D. Eisenhower, and Charles de Gaulle. Today, Pennsylvania Castle Estate offers luxury accommodation, dining, and event hosting services, with village amenities nearby and Weymouth just seven miles away.
